How the world uses freshwater: • about 70 percent for irrigation • about 20 percent for industry • about 10 percent for domestic use
Water resource management impacts almost all aspects of the economy, in particular, health, food production and security, domestic water supply and sanitation, energy, industry and environmental sustainability.
In 2030, 47% of world population will be living in areas of high water stress. Most population growth will occur in developing countries, mainly in regions that are already experiencing water stress and in areas with limited access to safe drinking water and adequate sanitation facilities.
Water scarcity already affects almost every continent and more than 40 percent of the people on our planet. By 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, and two-thirds of the world’s population could be living under water stressed conditions.
Humans are over-consuming natural resources at an unsustainable rate. Around 3.5 planets Earth would be needed to sustain a global population achieving the current lifestyle of the average European or North American.
The total usable freshwater supply for ecosystems and humans is about 200 000 km3 of water - less than 1 percent of all freshwater resources.
Freshwater lakes and rivers contain an estimated 105 000 km3 or around 0.3 percent of the world's freshwater.
Around 30 percent of the world's freshwater is stored underground in the form of groundwater (shallow and deep groundwater basins up to 2 000 metres, soil moisture, swamp water and permafrost). This constitutes about 97 percent of all the freshwater that is potentially available for human use.
